摘要：
The present invention relates to a method of separating an olefin from a gas stream, said gas stream comprising the olefin and at least one other component, said method comprising (i)compressing and cooling the gas stream; (ii) separating the olefin from the gas stream by absorbing the olefin in an absor-bent; (iii) separating the olefin from the absorbent by desorption; wherein compressing or cooling or compressing and cooling in (i) is carried out at least twice.
